a2hs.js

The Why?

As you probably know, iOS Safari doesn't have a built-in pop-up window with a suggestion to install a progressive web app on an iPhone/iPad (like Google Chrome). The a2hs.js project easily solves this problem!

Also, it's lightweight, production-ready, zero-configuration, has no dependencies and perfectly works with all of popular JavaScript frontend frameworks.

Install

npm install --save a2hs.js

Usage

/**
 * Import a2hs.js
 */
import AddToHomeScreen from "a2hs.js";

/**
 * Simple (with default config) init
 */
AddToHomeScreen();

/**
 * Advanced (with your config) init
 */
AddToHomeScreen({
  brandName: "Demo",
  fontFamily: "Tahoma, sans-serif",
  backgroundColor: "red",
  color: "white",
  // ... see full list of config options below
});
